Various versions of the song were uploaded by amateur singers, guitarists and DJs on social networking sites.

The song became a hit with approximately 5 million views on YouTube within 10 days of release, which helped in the marketing of the film. A happy romantic number, it brings the story of a lover sharing his happiness with the world ' while some critics call it a self-centred narration of a lover's heart along with a darkness.

Melodious and rhythmic, it has meaningful lyrics. Sung by Arijit Singh, it starts slowly but gradually picks up the pace. Arijit's voice does touch the listener's heart and lyrics support the passion as well.' IANS wrote, 'The album opens with 'Tum Hi Ho'. Composer Mithoon has penned the lyrics for this passionate ballad which might remind one of the rest of the Bhatt music that has been heard in abundance in recent times, right from Raaz 3 to Jism 2. The piano, strings, and beats are very effective in creating an eerie romantic atmosphere for the singer to transform the song and Arijit Singh does that magnificently.' Koimoi commented, 'Album opens with a heavy and deep voice of Arijit Singh crooning 'Tum Hi Ho'. A chartbusting musical experience indeed.' Planet Bollywood commented 'The song has all the hallmarks of a Mithoon creation it's soulful, extremely touching and of course it's dripping with melody. 'Tum Hi Ho' and ' Sunn Raha Hai' (both versions) are our favourites, but 'Chahun Main Ya Naa' and 'Piya Aaye Na' end up as a close second.
